Modular Drum Machine Creates Random Rhythms

Posted on by

Don’t worry, the rhythms themselves aren’t random! That would hardly make for a useful drum machine. [kbob]’s creation does have the ability to randomly generate functional rhythms, though, and it’s all done on a breadboard.

The core of this tiny drum machine is two Teensy dev boards. One is an FM synth tuned to sound like drums, and the other is a random rhythm generator with several controls. The algorithms are from Mutable Instruments’ open source Eurorack modules. The entire thing fits on a breadboard with JIGMOD modules for the user interface. The machine runs on lithium batteries in the …read more

Autonomous Musical Soundscapes from 42 Fans and 7 Lasers

Posted on by

[dmitry] writes in to let us know about a new project that combines lasers with fans and turns the resulting modulation of the light beams into an autonomous soundscape. The piece is called “divider” and is a large, wall-mounted set of rails upon which seven red lasers are mounted on one end with seven matching light sensors mounted on the other end. Interrupting the lasers’ paths are forty-two brushless fans. Four Arduino Megas control the unit.

Laser beams shining into light sensors don’t do much of anything on their own, but when spinning fan blades interrupt each laser beam it modulates the solid beams and turns the readings …read more

Hackaday Prize Entry: A Cute Synthesizer

Posted on by

For electronics aficionados, there are few devices cooler than music synthesizers. The first synths were baroque confabulations of opamps and ladder filters. In the 70s and 80s, synths began their inexorable march toward digitization. There were wavetable synths that stored samples on 27-series EPROMs. Synths on a chip, like the MOS 6581 “SID chip”, are still venerated today. For his Hackaday Prize entry, [Tim] is building his own synthesizer from scratch. It isn’t a copy of an old synth, instead it’s a completely modern synthesizer with a classic sound.

[Tim] is a former game developer and has already released a …read more

Curiously Delightful Things Done with Lasers and Projectors

Posted on by

Seb Lee-Delisle has built a career around large installations that use powerful lasers and high-end projects to make people happy. It’s a dream job that came to fruition through his multi-discipline skill set, his charismatic energy, and a mindset that drives him to see how he can push the boundaries of what is possible through live interaction.

His talk at the Hackaday | Belgrade conference is about his Laser Light Synth project, but we’re glad he also takes a detour into some of the other installations he’s built. The synth itself involves some very interesting iterative design to end up …read more
